MRAG have provided a CCAMLR Scientific Observer for the longline fishing vessel Koryo Maru 11 whilst fishing in SubArea 48.6 since 2010. The vessel fishes for Patagonian toothfish (Dissostichus eleginoides) and Antarctic toothfish (Dissostichus mawsoni) within the CCAMLR area.

The tasks carried out by the observer are outlined in the CCAMLR Scientific Observer Manual and include:

  • Recording the details of the vessel operations;

  • Taking representative samples of the catches to determine the biological characteristics;

  • Recording biological data by species caught;

  • Recording the by-catches, quantity and biological data;

  • Recording seabird and marine mammal entanglements and incidental mortalities;

  • Recording the procedure by which declared catch weights are measured;

  • Preparation of reports and submission to the appropriate authorities at CCAMLR;

  • Recording and reporting factual data on all sightings of unidentified vessels and illegal, unregulated and unlicensed (IUU) vessel in the CCAMLR Convention Area;

  • Collecting information on waste disposal (lost, discarded, or retained) to including offal and fishing gear;

  • Tagging of toothfish at the required rate;

  • Tagging of skate; and
